In Tunisia, there is no available data on the CVD risk profile in the children population, although it is well known that risk factor development takes place during childhood. We undertook an epidemiological survey based on a representative sample of 1569 urban school children of Sousse in Tunisia to assess the prevalence of hypercholesterolemia and other lipid disorders. Prevalence of hypercholesterolemia (8.1%), high level of LDL-cholesterol (3.9%), high level of Lp(a) (14.5%), hypertriglyceridemia (1.3%) and hyper Apo B (3.4%) were found. These informations will be useful to set up a regional program of Heart Health promotion in schools.
